Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718340, here are decompositions:

89 + 8718251 = 8718340
149 + 8718191 = 8718340
227 + 8718113 = 8718340
251 + 8718089 = 8718340
347 + 8717993 = 8718340
353 + 8717987 = 8718340
359 + 8717981 = 8718340
401 + 8717939 = 8718340

Showing the first eight; more decompositions exist.
